SASH FASTENER.

Application filed April 23, 1924.

T0 all tlf/1,0m 73;'1 may concern.'

Be it known that I, OLIN S. JOHNSON, a citizen of the United States, residingat APalermo, in the county of Butte and State of California, have invented new and useful Improvements in Sash Fasteners, of which the following is a specification.

'I his invention relates to improvements in sash fasteners and has particular reference to a sash fastener which may be attached to the side-rail of the sash in such a manner thatI the window will be automatically secured in any position to which the same may Le elevated.

The principal object of'this invention is to construct a device which can be readily applied to window-s not equipped with weights and serving to retain the window sash at any desired height.

Another object is to produce a device which is extremely simple in construction, conomical to manufacture, neat in appearance and a device which will not distigure the window.

A still further object is to produce a device of this character which may be applied by an unskilled person, thereby saving the cost of installation.

Other objects and advantages will be apparent during the course of the following` description.

In the. accompanying drawings forming a part of this specification, and in which like numerals are employed to designate like parts throughout the same.

Figure I is a side elevation of my sash fastener attached to a fragmentary portion of a window, and

Figure II is an end elevation looking in the direction of the arrow of Figure I.

In the accompanying drawings wherein for the purpose of illustration is shown a preferred embodiment of my invention, the numeral 5 designates the frame of a window, and the numeral 6 the sash thereof.

It is of course understood that the sash has the customary glass pane 7 yand is otherwise constructed in accordance with ordinary practice.

At 8 I have shown a base-plate secured Serial No. 708,551.

to the sash 6, which base plate has fastened thereto a U-shaped cover plate 9. Pivoted between these plates as at 12, is a lever 1l havingI a thumb piece 13. The opposite end of this lever has a contact piece 11i preferably formed of a resilient material such as rubber. A spring 16 serves to normally keep the contact piece 14 in contact with the window frame 5. This spring is best shown in Figure l where it will be noted that one end contacts the U-shaped cover plate 9, while the opposite end contacts a lug 17 formed upon the lever 11.

The operation of follows Assuming that the device has been attached to a sash, the sash may be lifted with the result that the Aontact piece 14 will .move along the window frame until the. sash comes to rest, after which time, the con` tact between the frame and the Contact piece will be sutiicient to maintain the sash in the elevated position.

lVhen it is desired to release the sash, the thumb piece 13 is pushed thus moving the contact piece 14; out of engagement with the window frame, thus permitting the sash to be lowered.

It .is to be understood that the form of my invention herewith shown and described is to be taken as a preferred example of the same, and that various changes in the shape, size and arrangement of parts may be resorted to without departing from the spirit of the invention or the scope of the subjoined claim.

HavingI thus described my invention, I claim In a device of the character described, a lever having a thumb-piece at one end, et resilient member secured to the opposite end of said lever, a base plate, a U-shaped cover plate, said lever being; pivoted between said base plate and said U-,shaped cover plate,` means for securing` said plates to a window sash in sucha manner that said contact member will contact the frame of the win` dow, for the purpose specified.

In testimony whereof I aiiiX my signature.

my device is as
